scripltlion.

T s invention relates to improvements in devices for the separation of light .matter from heavy liquids-such as cream, oils, fats, grease; and the like-the obj ect-being to provide a simple device particularly adapted for household use in separating cream from milk in bottles or other receptacles. I

- I will describe a liquid-separator embodying my invention and then point. out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this s ecification, in which similar characters of re erence indicate corresponding parts in all the figures. Figure 1 is a sectional elevation of a portion of a bottle with a separator embodying my invention in connection therewith. Fig. 2 is a section on the line a: w of Fig. 1, and

Fig. 3 is a side'view of the separator with the cover and parts carried thereby removed.

Referring to the drawings, 1 designates a bottle for containing milk or other liquid and having on its neck ortion an annular bead 2 to indicate the height the liquid should reach in the receptacle. The receiver for cream or other light material consists of a receiver 3, made of glass or other suitable material, and adapted to be engaged in the neck of the bottle or the like.

The interior of the bottle-neck at the top is provided with a lug 4'for engaging in any one of thevertical channels 5, 6, or 7, formed in the exterior of the receiver, these channels 'being of different lengths, so that the receiver may be inserted and held in the bottleneck at any desired depth, depending upon the time desired 'for the separation of cream' or the like from the heavy liquid. Also on the receiver is a scale 8,-designed to indicate by inches or ounces the amount of cream in the receiver, thus ascertaining the richness or uality of the milk when the device is use for receiving cream. Also on the exterior of the receiver is an annular-bead 9, which is designed to rest upon the upper end of a bottle-neck when the device is used in connection with a bottle not provided with the lug 4. Having screw-thread engagement Specification of Letters Patent.

with the upper end of the receiver is a cap 10 of suitable materialsuch, for instance,

as aluminium-andthis cap is provided with a vent 11 and an opening 12 for the pouring out of the cream or other material in the receiver. The'vent 11 and opening 12 may be closed by a swinging plate 13, having a finger-piece 14 at one end. This plate 13 has swinging movementon a valve-rod 15, the said valve-rod being screw-threaded to engage in a nut 16, secured to the inner side of the cap.

The upper end of the rod 15 is provided with a knob 17, and at the lower end is a conical valve 18 for engaging in an opening 19 in the bottom of the receiver, the walls'of said opening 19 being tapered to correspond to the shape of the valve. of cork or other suitable material, and it will be noted that the bottom of the receiver is double concave,so that the cream or other light material will be directed from the sides.

of the bottle or container to the opening 19. In the operation the receiver is to be placed This valve may be in the bottle, as indicated in Fig.1, and allowed to. stand for any desired length of time, so that the cream or other light matter will pass into the receiver. When the o eration is completed, thevalve 18 is to be c osed into the opening 19, when the receiver may be removed and the contents poured out.

By making the bottom double concave the cream will meet with no resistance and will drain to the last drop.-

While I have indicated my invention as in connection'with an ordinar milk-bottle orof a milk-bottle of the usuai quart size, it is to be understood that the device may be made in different sizes for difierent sizes of liquid-containers. r

' Iaving thus described my invention, I

claimasnew and desire to secure byLetters Patent v 1,. The combination with a liquid-receptacle, of a receiver for light liquid adapted to fit in the mouth of the receptacle, coacting mea'ns between said receptacle andreceiver for supporting the receiver, as it may be variously adjusted in the receptacle, the said receiver having an opening in the lower portion, and a valve for said 0 ening.

2. The combination wit a liquld-receptae cle having a lugformed in its neck ortion, of

a-receiver for cream or'like materia ,adapted' to engage in the neck, and having exterior channels for receiving said lug ,the said chan nels being of different lengths, the said receiver having an opening in its bottom, and a valve for closing said opening.

3. The combination with a bottle or the like having a lug in its neck portion, of a receiver for light liquid, adapted to engage in the neck of the bottle, the said receiver hav' ing an opening in its bottom, and also having exterior channels, in any one of which said lug is designed to engage, the channels being' of different lengths, ascale on the receiver, and avalve for closing the opening in the bottom of the receiver.

'4'. A- separator comprising areceiver ada ted toengage inthe opening of a bottle or t' e-like, the said receiver having a double 1 concave bottom provided with an opening, a removable cap for the receiver, a nut secured to the inner side of said cap, a screw-rod engaged with said nut, a valv on the lower end of therod for engaging in th bottom opening, the said cap having openings, a swinging late for closing said openings, and an annuarbead on the exterior of the receiver. In testimony whereof I have signed my 2 5 name to this specification in the presence of two subscribingwitnesses.
